to_char(OF) is broken

Folks,

In to_char(), the new-in-9.4 'OF' feature is straight-up broken, to
wit:

set timezone to 'America/Caracas'; select to_char(now(), 'OF');
SET
 to_char
─────────
 -04:-30
 ^OK ^NOT OK

Interestingly, in git master as of yesterday, it's broken in an
entirely different way:

set timezone to 'America/Caracas'; select to_char(now(), 'OF');
SET
 to_char
─────────
 -004:30
  ^ What's this extra zero doing here?
(1 row)

Fractional offset time zones should probably be in our regression test
suite for this feature.

Cheers,
David.
